ASX Shareholder Moves to Sue Ex-Directors Over Failed Blockchain Plan

An Australian Securities Exchange (ASX) shareholder has moved toward legal action against former ASX directors and officers, seeking court permission to pursue claims tied to the exchange’s failed blockchain-based clearing and settlement replacement project.

According to an ASX announcement on Wednesday, Rosherville Pty Ltd has informed the exchange that it intends to apply for leave to commence a statutory derivative action under sections 236 and 237 of Australia’s Corporations Act. If the Federal Court grants permission, Rosherville would bring the proceedings on ASX’s behalf—while the court would first need to assess whether the proposed case can proceed.

Key takeaways

• Rosherville Pty Ltd is seeking Federal Court leave to bring a statutory derivative action on ASX’s behalf related to the CHESS replacement project.
• ASX said there are no allegations against the exchange itself in the proposed proceeding, but it has not disclosed which former officers or directors are targeted.
• The push comes after ASIC took legal action over allegedly misleading market statements connected to the project and after ASX admitted misleading conduct.
• The dispute could clarify how far shareholders may hold former leaders accountable for oversight of high-profile fintech failures.

How the CHESS blockchain plan unraveled

ASX began investigating a replacement for CHESS—the Clearing House Electronic Subregister System—in 2016. The exchange selected a distributed-ledger approach developed with New York-based Digital Asset, with expectations at the time that ASX could become one of the first major securities markets to run core services on blockchain technology.

Those expectations ultimately did not materialize. The rollout was repeatedly delayed. In November 2022, ASX paused the project after an Accenture review identified significant issues, including problems with the design and with its ability to satisfy ASX requirements, according to reporting at the time from Cointelegraph.

By May 2023, ASX had formally abandoned the blockchain replacement plan and said it would shift to more conventional technology, another step covered in earlier reporting on the matter.

Regulator action over market statements

The Federal Court and ASIC’s involvement is central to the latest shareholder development. ASIC sued ASX in August 2024, alleging that ASX lacked a reasonable basis for statements made in February 2022 that the project was “progressing well” and on track for an April 2023 launch.

ASIC characterized the matter as a collective failure involving ASX’s board and senior executives, according to earlier coverage. The dispute culminated in a significant regulatory outcome for ASX: in June 2026, ASX admitted misleading conduct connected to the CHESS replacement project.

On July 3, the Federal Court ordered ASX to pay a $14.4 million penalty and $2.1 million toward ASIC’s costs, effectively closing the regulator’s case weeks before Rosherville notified ASX that it was preparing to seek leave for derivative proceedings against former officials.

Why a shareholder derivative action matters

ASX’s Wednesday statement underscored that the proposed lawsuit is aimed at individuals rather than the exchange itself. It also made clear that the matter is at an early stage: the exchange did not specify which former officers or directors Rosherville plans to target, and it did not outline the precise alleged breaches or the remedies the claimant wants. Importantly, the court had not yet considered whether the proposed action can proceed.

Even so, the direction of the case highlights a question that investors and corporate governance observers often consider after large-scale technology undertakings fail: when a company admits misconduct or faces penalties tied to project communications, can shareholders translate that outcome into claims against the decision-makers who oversaw the effort?

As framed in ASX’s disclosure, Rosherville’s plan is grounded in Australia’s Corporations Act mechanism for statutory derivative actions, which can allow shareholders to pursue claims on behalf of the company, subject to court approval. That “permission” step is critical—because it means the court will examine whether the case is procedurally and substantively viable before any allegations against individuals are litigated.

What to watch next in the Federal Court

For market participants, the immediate variables are straightforward. The court will determine whether Rosherville’s application meets the statutory threshold for leave and whether the claims can move forward. ASX’s statement indicates that the exchange itself is not accused in the proposed action, but it has declined to offer details about the individuals or the alleged duty breaches. That information, if provided later in the process, could determine how investors interpret the scope of accountability sought by shareholders.

Beyond the legal mechanics, the broader watch point is how the case interacts with the earlier ASIC matter. While ASX’s admission of misleading conduct and the Federal Court’s penalty are part of the background, the shareholder action—if permitted—would focus on the alleged actions or omissions of former officers and directors. Readers should monitor any court filings that clarify the specific duties in question and how the shareholder claim relates to, or differs from, the conduct ASIC pursued.
